Title: Sealed cabinet
Inventor: DONARUDO CHIYAARESU ERIOTSUTO
IPC: H05K9/00
Filed: 1989-01-24
Abstract: PURPOSE: To control the amount of compression applied to a seal and to prevent a door from being distorted by connecting a plurality of latch groups provided at the door, initially moving all nibs to a latch position by latching, and operating the individual latch and moving each nib. CONSTITUTION: When a handle 14 is rotated, a nib 12 moves and is engaged at the rear of a striker plate 35 of a door 25, and at the same time a connection rod 36 moves the nib 12 of other latches owing to the operation of an arm 12' of a central latch 32 but cannot move to other latches even if the handle 14 of the central latch 32 continues to be rotated. Then, by rotating all handles 14 to a lock position, load required for compressing the seal of the door fully is dispersed over each of five handles, thus reducing the damage to the door or the seal and at the same time giving a proper degree of compression to the seal.

Patent JP-H11215112-A (JP)
Title: Pll circuit
Inventor: TAKEYARI RIYOUJI
IPC: H03L7/091
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a PLL circuit where a loop gain changes in accordance with a transmission speed but is constant if the appearance frequency of a code transition point changes by arranging a sample-and-hold circuit and a variable gain amplifier in a feedback loop. SOLUTION: A sample-and-hold circuit 2 and a variable gain amplifier 3 are arranged in a feedback loop. The sample-and-hold circuit 2 samples the phase difference signal of an output of a phase comparator 1 at the time of data transition and holds it while there is no data transition. The variable gain amplifier 3 changes the level of the phase difference signal of the output of the sample-and-hold circuit 2 by changing the loop gain in response to transmission speed information of data supplied from outside of a PLL circuit. Since the variable gain amplifier 3 is included to control the gain in proportion to the data transmission, the loop gain is proportional to the data transmission speed. Thus, a jitter transfer area becomes proportional to the data speed and a Q value becomes constant irrespective of the transfer speed.

Title: Variable capacity flywheel
Inventor: SAKA MASAKI
IPC: F02N5/04
Filed: 1982-02-02
Abstract: PURPOSE:To avoid the necessity of large-capacity storage batteries and generators which were required in the former, by performing engagement of main and subflywheels by means of the magnetic flux generated from the core member consisting of a permanent magnet and releasing said engagement by deenergizing the magnetic flux of the core member. CONSTITUTION:In the low revolution number range in which an engine is started and the number of revolutions of the engine reaches the revolution numbers  for releasing a clutch, the current induced in an AC generating clutch coil 10 by the revolution of a main flywheel 4 is consumed in a resistor 34, thus preventing a high voltage from beind induced in the coil 10. Therefore, the main and the sub-flywheels 4 and 17 are integrally revolved in the engaged state. When the number of revolutions of the engine reaches the high speed revolution number range, the current induced in the coil 10 is supplied into a clutch field coil 13, and the magnetic flux of a permanent magnet coil 12 is offset by said electric current, and the main and the sub-flywheel 4 and 17 are brought into the released state.

Title: Digital equalizer
Inventor: KIMURA HIDEKI
IPC: H04B3/06
Filed: 1989-01-24
Abstract: PURPOSE:To improve economy by truncating the start part and the end part of a coefficient string which is convolution-operated so as to reduce the total number of the coefficients, convoluting the coefficient string into input data and changing the bands of more than two into objective characteristics. CONSTITUTION:The equalizer consists of a coefficient convolution arithmetic circuit 1, a coefficient truncating arithmetic circuit 2, a coefficient transfer circuit 3 and an FIR (non-cyclic type) filter 4. A signal X(n) inputted to the FIR filter 4 is audio data expressed by 16 bits, when the digital equalizer 10 is used as a digital graphic equalizer for audio, for example. An output signal Y(n) is also audio data which is processed in the FIR filter 4 and which is expressed by 16 bits, for example. Since the normal transmitting characteristic can be realized by less product sum arithmetic circuits or the coefficient convolution arithmetic circuit 1 by the combination of a multiplier and an accumulator, economy can considerably improved.

Title: Photo switch
Inventor: MATSUMOTO TAKAO
IPC: G02B27/28
Filed: 1979-02-13
Abstract: PURPOSE: To achieve the improvement in stability by performing optical path changeover through direction changing of external magnetization.  
     CONSTITUTION: A Faraday element 5 and compensating plate 6 varying by 45° with external magnetic field H in the deflection ditections of incident light and exit light and the polarizing prims 3, 4 worked the end planes at a right angle to the advancing direction of light are opposedly disposed on the right and left of the reflecting mirrors 7, 8 opposedly disposed above and below. As a result of this, if the light advances from the left to the right at the time when it passes both of the Faraday element 5 and compensating plate 6, the polarizing direction of light does not change owing to the mutual offset effect but if it advances from the right to the left, the mutual rotatory light overlaps and the polarization direction of light rotates by 90°. On the other hand, if the direction of the external magnetic field H is reversed, the opposite phenomenon occurs, thus the optical path change-over function is provided by the direction change of the external magnetic field.

Title: Load detecting device for wining device
Inventor: GOMI KIYOSHI
IPC: B66D3/24
Filed: 1986-01-29
Abstract: PURPOSE:To detect a real suspension load even during an acceleration period by finding a value corresponding to the degree of variation in the moving speed of a rope for suspending the load and a value corresponding to the load placed on the rope and performing arithmetic operation based upon a specific expres sion. CONSTITUTION:When the load 1 placed on a floor is suspended through the operation of the winding device, a flywheel 21 rotates and a torque detector 22 detects torque T. Further, a load detector 10 detects the suspension load P placed on the rope 3. Then, an arithmetic means 31 calculates an equation W=P(1/(1+K'T)) and outputs a signal W corresponding to the real suspension load after inertial force due to acceleration is removed. In the equation, K' is a coefficient. Then, a comparing means 32 outputs a signal which commands the operation of the winding device when the signal W is larger then a rated value. Consequently, the operation of the winding device is stopped automatically or manually. Therefore, when the operation for lifting is only started, the real suspension load is found immediately and when the load is larger than a rated load, the operation is stopped immediately, thereby preventing an accident from occurring.
